I just purchased a used 2004 Montana. I'd like to be able to use the XM radio feature on it.
I am a current XM subscriber.
I can't find the radio ID number to proceed with the XM subscription for the car.
Any idea how to find it? I've done exactly as the manual said to do -- nothing.
Before XM can activate my subscription, I must be able to provide the radio ID number.
Do you know where I can find it? It was suggested that I take it to a Pontiac dealersihp,
but if I can save money by finding it myself, I'd like to!
Thanks!
